LOCK.

SPECIFICATION forming part of Letters Patent No. 764,014, dated July 5, 1904.

Application fi1ed April 5, 1902. Serial No. 101,495. (No model.)-

To all whmn it may I rmccrm Be it known that we, \VILLIAM E. SPARKS and OLIVER F. SPARKS, citizens of the United States, residing at New Haven, in the county of New Haven and State of Connecticut, have invented certain new-and useful Improvements in Locks, of which the following is a specification, reference being had therein to the accompanying drawings.

Our invention relates to improvements in locks, and has for its object, among other' things, to provide-a lockwhich can be attached to doors of varying thicknesses with the minimum amount of cutting of the stile thereof, to provide means whereby the parts of the lock upon either side of the door will ali tie with each other irrespective of the thickness of the door, to'operatively connect the several parts of the lock in such a manner that the lock can be attached to the door without removing any of them, and, further, to so design the several parts that they may be economically constructed and readily assembled and when attached to the door the lock will be both neat and pleasing in appearance. To these and other ends our invention consists in the lock having certain details of com struction and combination of parts, as will he hereinafter described, and more particularly pointed out in the claims.

Referring to the drawings, in which like numerals designate like parts in the several figures, Figure 1 is a view of the inside of the door with our improved lock attached thereto. Fig. 2 is an edge view thereof, and Fig. 3 is view'of the outside of the door. Fig. 1 is a perspective View of the stile of a door readyto attach our lock thereto. Fig. 5 is a vertical section of our lock and' the door upon line A B of Figs. 1 and 3. Fig. 6 is a view of the interior of the inside case. Fig. 7 is an elevation of the inside of the front plate.

Fig. 8 is' a transverse sectional view of the lock and door upon line AB of Fig. 5. Fig. 9 is a detailed view of the stop mechanism. Fig. 10 is an elevation of the inside of the upper part of the front plate. Fig. 11, is a detailed view of the cylinder-retaining pla e Fig. 12 is a perspective view of the key-bar,

plates 8. through the aperture 1 from the front the reand Fig. 13 is a perspective view of the keybai' retainii'ig cl'i p.

Referringtcr the drawings, the numeral 1 designates the front plate, havinga boss 2 thereon. 3 the key-cylinder, and 9 the rose common tocylinder-locks. The cylinder 3 projects through the said front plate and is securely fastened thereto, said means comprising an aperture 1 through the plate 1 and corresponding in shape to that of the contour of a transverse section of the cylinder, and concentric with said aperture upon the inner side of said plate is a circular recess 5, ears 6, having the screws 7 threaded therethrough integral with said cylinder, and the retaining- After the cylinder has been passed taming-plates 8 are placed within the recess 5 upon either side of the cylinder, covering said aperture, and thereby prevent the withdrawal of said cylinder, and by the engagement of the points of screws 7 with the exposed face of the retaining-plates said plates are held against displacement and the cylinder is firmly and rigidly secured against movement. The outside knob 10 is provided with a shank 11, which passes through and is rotatable within the boss 2 and is held against end wise movement therein by the disk 12, secured to the end of said shank within arecess, in the front plate. Extending axially through the disk 12 and shank 11 1s a rectangular hole for the knob-spimlle 13.

The detailed construction of the key-cylinder is not herein shown and described because it is immaterial to our invention, as any of the common and well-known forms of cylinders for pin-locks can be used equally as well,

as the one" shown.

Upon the inside of the door is the case or inside plate 1-1, having inwardly-turned edges, with an offset 15 projecting laterally therefrom, which is designed to reach to the edge of the door, and on the end of said offset is an inwardly-turned lip or flange 16. A shallow mortise of less width than the thickness of the door is out in the edge thereof, Fig. 4,'for this lip or flange 16 and is the only part co'nvnected with the lock that requires mortising.

Movahly mounted within the erase it and oliset is the latch-bolt i7 the head of which projects through the lip 16 and normally held in such position by the springs 57. The rear end of the latch-bolt terminates in the yoke 18, and integral therewith are the up wardly-projecting followerdugs l9 and the laterally-projecting socket-lugs 20;

Rotatably mounted within the hub 21 upon the case 14 is the shank 22 of the inside knob 23, and attached to the inner end of said shank by the screw 25 and washer 26, Fig. 5, is the follower 2 1, of the usual construction and having two radial arms, each of which engages withone of the follower-lugs 19.

Fixed upon the end of the spindle 13 is the socket 27, having a radial arm 28 thereon, which projects into the path of one of the socket lugs 20. This socket is rotata'hly mounted on the lug 29 and within the cap 30,

fastened lugs 32 by the screws 81. The l rgi socket 33 is also provided with a radial arm 3a, which projects into the path of one of the socket-lugs 20 and is rotatably mounted on the lug 38 and within the cap 35, fastened by the screws 36 'to lugs 37 A lateral movement of the sockets 2 7 and 33 is prevented by the caps and 35, respectively. "ifhe key-- socket has a if notch 39 in the outer thereof, which opens into the interior of said socket through the slot 40.. Passing through the slot ll) and connecting the key-socket 33 with the cylinder 3' is the key loar 41, which is rigidly secured to the inner end of said cyl inder and is slidahle within the slot 40. The special means -for attaching the key-ha to the cylinder is immaterial to our invention, but, as herein shown, consists of a retaining 'clip 42, fastened to the end of the cylinder by a screw 43 and having a recess a l in one edge thereof of the same width as the head 45 of the key-bar i1 and a lug 4C6 projecting from the bottom of the recess it, which lug passes through a hole 47 in the key-bar and is then turned over, as shown in Fig. 13, and thus holds said key-bar rigid upon said cylinder.

The stop mechanism for preventing the operation of the latch-bolt by the outside knob 10. consists of the stop-bar e8, movable hetween'the lugs 32 and 49 and having a stop shoulder 50 thereon a finger-button 51, which passes through transverse slot in the case 1d and threaded into the stopdaar, Fig. 5, and a flat spring 53 withinthe recess 52, which engages a lug 5% on the case 1 and prevents the accidental movement of said stop-shoulder.

One side of the spindle-socket 2'? is flattened at 55, and when the knob is in its normal po sition, with the edge of the radial arm 28 engaging the stop 56, the face of the stop-shoulder 50 and the face 55 are in the same plane, and by shifting-the stop-bar transversely the saidstop-shoulderis moved under the face 55 and holds the socket-spindle and outside knob against rotation. The latch-bolt can only he that falls fairly within the spirit'and scope oi "letters operated now from the outside by means of a key placed in the cylinder 3. The rotation of the cylinder by a key, as is usual, also r0 tates the key-socket 33 through the key-"bar all and actuates the latch-bolt through the en gageinont of the'radial arm 34 and one of the socket-lugs 20. The latch-bolt can always he operated from the inside by rotating the knob 23, the engagement of the radial arms upon the follower 24- with the follower-lugs 19 ac- I tuating the latch-bolt.

the construction above described all of the lock parts are sov secured to either the front or inside plates that it is not necessaryto remove any of them to attach the lock to the door. i I

To insure the positive aline nent of the two plates in relation to each other and also to prevent rotary inovementof the plates with relation to each other, we have provided the posts 58 upon the plate 2 and the sockets o9' upon the case it, preferably arranged at or near both ends of the plates, the posts-heing fitted telescopically within the sockets and the plates being ri idly secured together by means'of screws 60, which pass through the case 14: and. are threaded into the sockets 59.

As the posts 58 are slidable within the sockets 59, the spindle 18 movable endwise within the shank of the knob 10, and the hit 4C1 movable within the key-socket 38, the lock can he used upon any door irrespective of its thickness.

'"We do not desire to be limited to the construction. hereinshown for positively alining the two platesbecause a variety of other means can he used equally as wel Forenaniple, a rectangular post could he used and fitted into a socket hi r hole.

To prepare the door ror our lock, r slim ply necessary to here two round holes fill through the stile thereof for the sockets oil and posts 58 and a similar hole 65?. for socket 33, key-bar all, and the'inner end of the cylin der 2- and a hole for the spindle 13. The size ol these holes is immaterial, provided they are sufficiently large to permit of the'en'trance of the several parts. In the edge of the door upon the inner side a recess 64: is cut to permit of the operation of the latch-bolt.

@ur improved lock can be secured to door with the minimum amount of cutting and without weakening the stile in the slightest degree, and the old niethodsoi' mortising or cutting a notch through. the edge of the door tion herein shown and described, hutclsim all our invention.
